sports feilds

hi everyone, can someone help me? right now, my programs consist of a pre em, fert, weed control, fert, fert, merit, fert, winterizer. now, i may have an opportunity to maintain some sports fields next season(soccor, baseball, football fields) should i be doing anything differently? maybe add a couple fungicides? any help, would be appreciated

I supply sport turf managers from the lowest budget NYC PS sand lots to the finest Pro stadiums & just about everything in between.
Stradegies are differnet because of use diciplines (or lack thereof).
Can you be specific as to the use schedule & (perhaps most important) the budget constraints?
